Application filed November This invention relates t-o a machine forconditioning yarn, the principal objects of which are to provide meansfor the continuous movement of the yarn in the machine after it isloaded; to provide means to treat it with an even spray of steamthroughout its course and throughout t-he machine; to provide means inthe form of a battle plate for preventing the steam to a certain extentfrom being discharged from the machine while the filling boxes are beingloaded into it and taken out; and to provide convenient means forconnecting the device with a well known form of stopping device forstopping it each time a box of yarn comes to the discharge position.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying dra-wings in which Fig. 1 isan end view of a machine embodying this invention;

Fig. 2 is a side view;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2;

Fig. 4 is a sectional view on the line 4 4 of Fig. 3, and Y F ig. ,5 isa plan of a part of the stopping device.

The machine is shown as comprising a casing or frame 10 which is closedon all sides and has `an opening 11 with a door 12 for loading andunloading the machine. Inside the machine is provided with a hollowshaft 13 on which is supported the means for carrying the yarn whichinvolves two spiders 14 in the form of spokes which carry two rings 15.Between these rings are a series of rods 16 on which are pivotedcarriers 17. Each of these comprises a bottom or shelf which is held bygravity in horizontal position at all times to receive the boxes of yarnupon them and carry them around as the shaft rotates. They are connectedwith the rods 16 by links 18 situated on both sides of the pivot of therods and also connected to the bottoms of the carriers at oppositesides. In this way the several carriers will assume the position shownin Fig. 3 at all times.

The shaft is hollow and is connected with a steam pipe 20 forintroducing steam therein and is also provided with a series ofperforated radial steam pipes 21 which are ar- PATENT OFFICE. i

ranged in several planes and are perforated throughout their areas andmay be plugged at the end. These steam pipes revolve, of course, withthe shaft and they produce an even spray of steam which is delivered toall the carriers which support theboxes offlling yarn deposited thereon.There is also a' stationary baie plate 22 located in position where itwill not be engaged by the rotary carrier or the supports forthe fillingboxes to prevent as much as possible the steam from passing out throughthe outlet 11 when the device is stopped for the purpose of loading orunloading.. This plate 22 is supported on arms .23 carried by necks onthe shaft boxes, which necks project through the casmg.

The driving shaft 24 is operated from-` some source of power by a pulley25 or equivalent device and it is provided rwith a clutch 26. Thisclutch can be pushed and closed to connect it with a shaft 27 arrangedend to end with respect to the shaft 24. The shaft 27 has a worm 28meshing with a worm wheel 29 fixed on the shaft' 13 on which thecarriers are located. The method of rota-V tion therefore will beobvious. p y

The clutch is operated by a leverV 30 which is connected by a slot andpivot connection 31 with the starting rod 32. To close the clutch, thestarting rod is pushed to the right in Fig. 1 by a handle on either end.y

On the shaft 27 is another worm 33 which meshes with a worm gear 34,which by a shaft drives a knock-off gear 35. knock-olf gear 35 mesheswith another spur gear 36 in line with it. When the gear 35 makes a;complete revolution, a tooth 37 on each of these gears willv come intocont-act. This action pushes the gearv 36 bodily away from the gear V35,the gear 36 being mounted in a bearing on a spring pressed pivoted lever38 for that purpose. This moves the lever 38 to the position shown infull lines in Fig. 5. This pushes a spring 40 out of engagement with anotch in the slot 39; This releases the spring 40 and allows this springto expand against a bracket 41 on the rod 32 and push this bracket andconsequently the rod to the left to release the clutch and stop themachine. This stopping mechanism by itself is called a candlestick stopmotion. The result is to stop the frame and the operator then takes outa box The of yarn on the support nearest the opening 11 and replaces itby another one and then pushes the starting rod again. The operatorcontinues to change the boxes as'the twelfth of a revolution of thedrum.

-. Y In this way all the yarn is treated the same length of time so thata uniform product is secured. The yarn is thoroughly sprayed with finesteam spray all the time and very little steam is lost through theopening for loading andunloading the machine. This constitutes anaccurate machine for doing this work and involves comparatively a smallamount of mechanism.

Although I have illustrated and described only a single form of theinvention, I am aware of. the fact that modifications can be madetherein by any person skilled in the art. without departing from thescope of the invention as expressed in the claims. Also other stopmotions can be substituted for the Candlestick stop motion shown.Therefore, I do not wish to be limited to all the details ofconstruction herein shown and described, but what I do claim is l; In ayarn conditioning machine,` the j combination with a casing, ahorizontal shaft therein and a frame on the shaft, of a series ofsupports pivotally depending from the frame around its circumference forreceiving the boxes of yarn to be conditioned, the shaft being hollow,means for introducing steam into the shaft and means carried by theshaft for distributing the steam in the form of jets uniformly in thecasing.
